Thank you for all of your feedback.
The car has only done 48K and has been serviced by BMW main dealers. I have only had the car since August but have noticed that it does seem a bit sluggish and jerky when pulling away from a standiing start. I previously owned a V6 ford Mondeo that was very quick on gear changes.
I don't really want to burn out the clutch so am thinking after reading the first reply that by taking out the cdv that could cause some expensive problems. I will get the car looked at soon and get the oil changed as suggested and see if that helps. Just hope ther is not a more serious problem lerking.
Thank you again for your assistance being a girlie find it quite confusing sometimes. I didn't realise just how much different a BMW engine is compared to other cars but I do love him.
